Can you drink out of polymer clay?

Polymer clay is a versatile material often used in crafting to create various items such as jewelry, sculptures, and decorative pieces. However, when it comes to using polymer clay for beverage containers like cups or mugs, questions arise regarding its safety and suitability. In this article, we’ll delve into the considerations surrounding the use of polymer clay for drinkware and discuss whether it’s a viable option.

1. Material Composition

Understanding the Components:

Plasticizers and chemicals:

Polymer clay consists of a combination of polymerized plastic particles and plasticizers, which are additives that make the clay pliable and easy to work with. While polymer clay is generally considered safe for crafting projects, it’s important to note that some brands and types of polymer clay may contain chemicals that could potentially leach into liquids.

2. Heat Resistance

Baking Process:

Solidification and safety:

Polymer clay is intended to be baked at specific temperatures to achieve its desired hardness and durability. When polymer clay is properly baked, it undergoes a chemical transformation that results in its solidification. While baked polymer clay is heat-safe, it’s important to consider whether prolonged exposure to hot liquids or dishwashing could affect the clay’s appearance or integrity.

3. Food Safety Regulations

Regulatory Considerations:

Compliance with food safety standards:

Polymer clay is not typically tested or certified for food safety by regulatory agencies. If you’re considering using polymer clay for drinkware, it’s essential to be aware of the potential risks and to exercise caution. It’s advisable to avoid direct contact between polymer clay and liquids meant for consumption.

4. Alternative Approaches

Coating or Sealing:

Adding protective layers:

If you’re determined to use polymer clay for beverage containers, some crafters choose to coat or seal the interior of the container with a food-safe sealant or epoxy resin. This can create a barrier between the clay and the liquid, reducing the risk of direct contact and potential leaching of chemicals.


While polymer clay is a popular and versatile crafting material, its suitability for drinkware is a topic that requires careful consideration. Due to potential risks associated with the materials used in polymer clay and the lack of regulatory food safety standards, it’s advisable to err on the side of caution and avoid using polymer clay for items intended for consumption. If you’re seeking personalized and safe drinkware, it’s recommended to explore alternative materials that are specifically designed and certified for food contact.
